Chemical Structure
Description
As a certified reference material (CRM), 5-Methoxy-2,2-dimethyl-3,4-dihydronaphthalen-1(2H)-one meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
5-Methoxy-2,2-dimethyl-3,4-dihydronaphthalen-1(2H)-one (CAS 21568-64-9) is a high-purity analytical reference standard with the molecular formula C13H16O2 and a molecular weight of 204.26 g/mol.
5-Methoxy-2,2-dimethyl-3,4-dihydronaphthalen-1(2H)-one (C13H16O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. Its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
